ANSWER Hello Merle. You will need to disconnect the power to the unit. Then remove the door off the machine and the front panel. Once the front panel is removed, you will need to remove the front shroud assembly. Next you will need to remove the belt from the drum assembly. Be sure and look at how the belt is run around the pulleys for reinstall. Once the belt is removed, you will need to remove the drum from the dryer. You should be able to access the tension pulley now. You will need to remove the c-clip from the front of the pulley shaft. Remove the pulley and install the new pulley. Reinstall in reverse order. Hope this helps.
